Convenient synthesis of a surface-active alkoxyamine-initiator from styrene oxide Living/free-radical polymerization of styrene and n-butyl acrylate

Abstract

A novel alkoxyamine based on N-tert-butyl-1-diethylphosphono-2,2-dimethylpropyl nitroxide (DEPN) has been designed with a functional group, which promotes the chemisorption of free silanols from silicon surface and organicinorganic hybrid materials by a sol-gel process. This alkoxyamine has been synthesized in high yield from styrene oxide and has been employed for the nitroxide-mediated polymerization of styrene and n-butyl acrylate. The resulting alkoxysilane-containing homo- and copolymer precursors have been shown to have narrow molecular weight distributions.
